The utility model content
The purpose of this utility model is exactly the deficiency that will solve the above-mentioned background technology, provides a kind of system that transposes from heavy and light, the simple immersed tube tunnel tube coupling axis positioning system that reaches convenient and reliable operation of composition.
The technical solution of the utility model is: a kind of immersed tube tunnel tube coupling axis positioning system, comprise that being fixedly installed on immersed tube saves the first steel end housing of end, non-butt end and be fixedly installed on the second steel end housing on the end, non-butt end for the treatment of the immersed tube joint, be provided with waterstop between described the first steel end housing and the second steel end housing, its special character is: described immersed tube joint and treat that the butt end of immersed tube joint leaves the space, the end, butt end of immersed tube joint is provided with device for limiting expansion.
In such scheme:
Described device for limiting expansion comprises spacing jack, and described spacing jack is fixed in the spacing jacking bracket, and spacing jacking bracket is fixedly connected on the end, butt end that immersed tube has saved by spacing jacking bracket dowel.
The first described steel end housing is fixedly connected on by the first steel end housing dowel that immersed tube saves on the end, non-butt end, and the second steel end housing is fixedly connected on the end, non-butt end for the treatment of the immersed tube joint by the second steel end housing dowel.
Described waterstop is the GINA waterstop, and the GINA waterstop can well adapt to the inhomogeneous distortion that produces of pipeline section, has good stagnant water effect.
During concrete the use, after the immersed tube joint is finished the locking backfill, by holing through survey the actual coordinate value on the butt end drift angle angle point of heavy pipe and design coordinate figure are compared, can find that the immersed tube joint exists certain misalignment of axe (deviate is in permissible value).For avoiding occurring larger axis cumulative departure, be arranged in the piston masthead amount of the stretching difference of the spacing jack on the drift angle of heavy pipe butt end by accurate control, cause and be fixed in the chrominance signal for the treatment of the GINA waterstop on the immersed tube joint steel end housing, thereby make the deviation of the non-butt end off-design immersed tube center line for the treatment of the immersed tube joint eliminate or adjust in the design deviation value of permission.
The utility model has the advantage of:
1, system is from heavy and light: compared to traditional gantry type tube coupling positioning system, the deadweight of novel positioning system greatly alleviates easy disassembly;
2, system forms simple: the system that simplifies arranges form, has simplified immersed tube tube coupling axis positioning working procedure, has improved efficiency of construction;
3, quantize correction control: owing to can accurately control the piston masthead amount of stretching that is arranged in the spacing jack on the drift angle of heavy pipe butt end, can make accurately control of tube coupling axis positioning.
4, compared to traditional gantry type tube coupling positioning system, novel positioning system architecture deadweight greatly alleviates, and is beneficial to the recovery operation.
The utlity model has the system that simplifies form is set, simplified immersed tube tube coupling axis positioning working procedure, improved efficiency of construction, system features in convenient is reliable, and tube coupling axis positioning ability is strong.
